As a fun project, I started developing an Android app for myself a few weeks ago, because I already missed Boost for Reddit, even though it's still usable. So I took Boost as an inspiration and started working. It's come quite far and I have decided to publish it on Google Play, in case others feel the same way. It's still lacking some features, most notably the ability to see when someone sent you a message or replied to your comments, as well as the ability to create posts, but for casual lurking it's already quite nice I think. It will hit Play Store in a fews days.
Yes, if it's on F-Droid I will try it out!
